BUCKET CONVEYER.

SPECIFICATION formingy part of Letters Patent No. 633,1 18, dated September 19, 1899.

Application filed October 27, 1898, serial No. 694,738. (No model.)

T0 a/ZZ whom zit may concern:

Beit known that I, CHARLES A. OASE, a citizen of the United States, and a resident of NewYork city, in the county of New York and State of New York, have invented certain new and useful Improvements in -B ucket Conveyers, of which the following is a specification.

This invention relates to improvements in bucket conveyers, and has for its object thc production of conveyer-buckets which can be easily turned to empty their contents and operate in conjunction with endless linked drive-chains.

To these ends my bucket conveyer consists of the particular construction and combination of parts, all as hereinafter described, and pointed out in the claims.

In the accompanying drawings like parts are designated by similar letters in the different views.

Figure l represents an elevation of my bucket conveyer. Figs. 2 and 3 show partial end Views. Fig. 4 shows an elevation, on an enlarged scale, of a portion of upper guiderails and adjacent guide-sheaves, with a portion of conveyer. Fig. 5 is a fragmentary plan of Fig. ft. Fig. 6 shows an elevation, on an enlarged scale, of sprocket-wheel driver, with a portion of bucket conveyer. Fig. 7 is a fragmentary plan of Fig. 6. Fig. 8 shows an elevation of a portion of lower guide-rails. adjacent guide-sheaves, and conveyer. Fig. 9 shows an end view and fragmentary section of Fig. 8, taken on line y2 y2 of Fig. 8. Fig. 10 shows a section of conveyer, taken on line A of Fig. 1. Fig. 11 shows an elevation, on an enlarged scale, of one bucket. Fig. 12 represents a plan and fragmentary section of bucket with drive-chain. Figs. 13 and 1&1E show positions of a bucket during turning when passing over depressions in the track.

Referring to Fig. 1, d d' a2 show an upper horizontal track with a depression at a' and a curve at a2. A lower horizontal track is shown from b to b', where a double curve is'formed, the track rising at b', lowering at b2, curving at b3, and ascending to b4. A vertical run of track is shown from o to d, the said track terminating in curves at the extremities. A

similar track is shown from d to d. The

buckets arc shown at e supported on wheels f, driven by the endless linked drive-chains X, the connections between chains X and buckets c being secured by means of the pins g. The whole system is driven by the sprocketwheels B on the shaft B,which turns in the direction indicated by arrow, and the conveyer in the directions shown.

C, O, and O2 represent guide-sheaves for changing the directions of the conveyer, two of each of these guide-sheaves being placed on the saine axial line.

Although Fig. 1 shows the disposition of the conveyer-buckets forming, essentially, a rectangle, it is evident that the drivers and guide-sheaves C, C', and C2 can be located to form other figures. Only one depression a is shown in the track,whereas any number can be inserted, suitable means being employed to cover the depressions when it is not required to dump the buckets at the location of the depressions, the guide-rollers at the depressions being raised.

One of theimportant features of myinvention is the dumping device shown at a', where the depression in the upper track allows the forward wheels of the buckets to descend and enter the same while the 4buckets are being propelled in the direction shown by the arrows. The forward wheels are virtually pocketed in this depression, while the Wheels on the back end of bucket rise as the bucket is turned. Guide-rollers h prevent the linked chains rising at the point of turning. Guiderails could be substituted for the guide-rollers h'. l/Vhen the linked drive-chains move forward over the depressions in the tracks, thebuckets assume positions as shown in Figs. 13 and li and asat a in Fig. 1, and when the wheels return to the straight track beyond the depression the buckets are turned as shown at d.

An inspection of the bucket in the depression d clearly shows the means employed to turn the buckets, which is the effect produced by the forward wheels of the bucket impinging on the curve or depression and the pulling of the drive linked chains X, while the said chains are prevented from rising by the guide-rollers h.

Driving sprocket-wheels are shown at Bin IOG Figs. l, 3, (j, and 7. The wheels are secured to shaft B' and en gage the linked drive-chains X by means of the teeth i, working in the spaces inclosed by the outside links 7tand the ends of the opposite double center links Z. When the linked chains carry the buckets on the said sprocket-wheels, they are turned to upright positions, as shown at c2. When the buckets are carried under the guide-sheaves C, they still main tain their upright positions and are brought to the lower horizontal run of track in the same upright positions.

At the guidesheaves C' are shown guiderails which form a particular part of my invention. These guide-rails and sheaves are shown enlarged in Figs. 8 and 9. The track from b to b2 is formed into a double curve, rising at bl above the level of b and dropping below said level at b2, turning with an easy sweep at b3, and then ascending to b4. The double curve is provided to tip the end of the buckets, as e3, above the end 640i the bucket next adjacent, allowing the ascent of the buckets as they travel upward under the guide-sheaves C. Tithout this depression of the double curve the corner e4 might prevent the corner e3 from rising when under the sheaves C', because at this point the ends of the buckets, as e3 and e, approach each other, and the horizontal distance between the buckets is less than when on the straight portion of the track.

The guide-rails at c and b3 control the positions of one pair of wheels of the buckets, and guide-rails d and m control the other pair of wheels of the buckets, keeping the same upright as they are suspended from the linked drive-chains while being carried under the sheaves C'.

Referring to Figs. l and l, the guide-rails at a? and d control one pairot wheels of the buckets, and the guide-rails at c and n control the other pair ot wheels of the buckets, always maintaining them, as they move over the guide-sheaves C2 to the upper horizontal run of track, in upright positions. The guiderails d d and c c guide the buckets between the guide-sheaves C and C2.

Referring to Fig. l1, which shows an elevation of one of the buckets, on an enlarged scale, and Fig. l2, which represents a partial plan and section on line fc, it will be plainly seen that the wheels fare journaled to the sides of the buckets, an important feature ot my invention. A wheel base-casting f is fastened to the side plates of the buckets, into which are driven the journalpins gl, on which the wheels f turn. A cotter g3 secures the pin in place. The long boss f2 is cast with wheel base-castingf, into which the pins g are driven and are held by the cotters g2, the said pins g securing the buckets to the endless link-chains X. A collar is turned 011 the pins to prevent the linked drive-chains [rom getting out of place.

It is evident from an inspection of Figs. 1l and l2 that the linked drive-chains X and the wheels f can be easily detached from the wheel base-castings j" by removing the cotter pins g2 and g3.

Having described my invention, I claim as newl. A conveyer comprising buckets with wheels journaled thereto, endless linked drive-chains, and pins securing the buckets to the chains, in combination with tracks containing depressions for turning the buckets, and guide-rollers placed adjacent to said depressions in the tracks, substantially as described.

2. A conveyer comprising buckets with wheels journaled thereto, endless linked drive-chains, and pinsseeuring the buckets to the chains, tracks with depressions, in combination with guide-rails having double curves, and their adjacent guide-sheaves for tipping and righting the buckets, substantially as described.

4. A conveyer comprising buckets with wheels journaled thereto, endless linked drive-chains, pins securing the buckets to the chains, tracks with depressions and their adjacent guide-rollersfor turning the buckets, in combination with sprocket drive-wheels, guide-rails and their guide-sheaves, substantially as described.

A conveyer comprising buckets with wheel base-castings carrying journals and pins; wheels secured to the journals; linked drive-chains secured to the buckets by means of the pins; in combination with tracks containing depressions, and their adjacent guiderollers for turning the buckets; guide-rails and their adjacent guide-sheaves; sprocket drive-wheels; straight and curved sections of track, substantially as described.
